GQ0A021402JAT Description

The GQ0A021402JAT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and robust thermal performance. This 20-pin QSOP package features 10 isolated resistors, each with a 14K Ohm resistance, 5% tolerance, and a ±50ppm/°C temperature coefficient. Encased in a ceramic substrate, it offers superior thermal conductivity and mechanical durability. With a 1W total power rating (0.1W per resistor) and a 100V maximum voltage rating, it operates reliably across a wide temperature range of 70°C to 125°C. The gull-wing termination ensures secure surface-mount assembly, while the QSOP package (8.66mm x 6.02mm x 1.47mm) is optimized for space-constrained PCB designs.

GQ0A021402JAT Features

• Isolated Circuit Design (ISOL): Each resistor operates independently, reducing crosstalk and improving signal integrity.
• Thin-Film Technology: Delivers low noise, high stability, and tight tolerance (±5%) for precision circuits.
• Ceramic Case: Enhances thermal dissipation and withstands harsh environments.
• Wide Operating Range: Rated for -55°C to +125°C, derated to 70°C at full power.
